LElVIS J. TRIPP, OF MESICK, MICHIGAN.

DRYING-KILN.

To aZLwftom it may concern:

Be it knownthat I, LEWIS J. TRIPP, a citizen of the UnitedStates, residing at )Iesick,

in the county of VVexford and State of Michigan, have invented certain new and useful Improvements in Drying-Kilns, of which the following 1s a specification.

My invention relates to an improvement in drying-kilns, and i'sm0re particularly adapted for the drying of all kinds of woodenware; and it consists in: a room or chamber divided horizontally into two compartments, the lower of which is preferably" provided with tracks to receive a truck upon which the material to be dried is carried into and out of the kiln, and the upper compartment is provided with drying-coils of pipes, with a coldair duct at or near the center and airpassages at each end, with means at or near the center of the lower compartment or chamber for exhausting the a1r therefrom and in so doout and a perfect circulation of dry air.

My inventlon further COIISISIS in certain novel features of construction and. combinations of parts, which will be hereinafter described, and pointed out 111 the claims. I

The accompanying drawing is an interior view of the kiln, showing in perspectivethe arrangement of heating and circulating means and the division of the kiln into two compartments, one abovethe other.

The buildingmay be of any size and dimensions to suit the requirements and is prefe-rably provided witha door at each end for i the entrance and exit of a truck, (not shown,)

which is adapted to travel on tracks 1 1, on the floor of the kiln. At a suitable elevation above the floor, the upper floor 2 is rovided,

thus dividing the interior of the k' n into an upper and lower compartment 3 and 4, re spectively. This upper floor 2 preferably extends from side to side of the building, but leaves an air-space 5 at each end, as shown, for the circulation of the hot air downward from the upper compartment. this upper compartment are arranged an adequate number of steam-pipes 6 6. 'There are preferably two sets-of pipes, one at each end, and

the ends of these'pipes are provided withheaders 7 and ,8, the upper headers '7 being intended to receive the steam from the boiler, as indicated by the arrows, through the pipes 9 9, and the lower headers to return the steam and hot water to the boiler through pipes 10 10. -The pipes from the upper Specification of Letters Patent.

mg creating auniforni temperature through Patented Oct. 9, 1906.

REISSUED v headers 7 7 are coiled back and forth several times and finally discharge into the lower headers 8 8.

Air enters'at some central point, as at 11,,

culating the air proeeeds'as long as it is necessaryto continue the drying process.

I have heretofore tested the efficiency of this kiln and find that it afl'ords a perfect and uniform heating and circulating, distribution, and application of the air. At the same time the kiln is simple in its construction and economical in the parts required and in the heating-and distribution of the-air.

Slight changes might of course be made in the, form and arrangements of the several parts described without departure from the,

spirit and scope of my invention, and hence I do not wish to limit myself to the exact con-' struction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is- I 1. A dry-kiln comprising a house divided horizontally into two chambers, air-passages at op osite points in the-floor of the chamber, means located at opposite en s of the upper chamber for heating the air and inlets and outlets for the air centrally located in the upper and lower compartments whereby the co d air is heated during its passageto the air-outlets in the floor of the upper compartment whereuponit is drawn endwise in opposite directions through the lower cornpartment and discharged ator near the center thereof;

2. A dry-kiln comprising a house divided horizontally into two compartments in communication with each other at o posite points, one compartment having heating means therein adjacent to said communicating-points, an air-inlet in the compartment for the heatin apparatus located at a central point an an air-exhaust in the other g I I 833,011

5' that the stock is subjected to an even tem- Witnesses: I

per'etul e all through the kiln. I :ELMER E. GODFREY,
